Lol I miss my NPCC camps ;_; nope you can make a RMT as your first post but most likely people don't read the rules... Just make sure you read the rules before posting! :) Also, play on Smogon's server for OU >.> PO isn't that good in standard from what I've heard.
Bulbapedia archives is where you can search for official (and big) Pokemon art. Sprites are enough actually. Unless you want a banner, then that's a different thing haha.
